I bought lenevo hw01 fitness band from flipkart yesterday. the using of this bamd is to jser friendly and the battery back time is very long. it just decreaaes only 14% of charge from last day. the step counter, heqrtrate monitor, and othe notifications are really awesome with smooth experience. The OLED display gives you a very long backup with smooth experience.it feels premium and the built quality is really enough good what I hvn’t expected.
